Abstract.

W bosons can be produced in the channels \(e^\pm p\to W^\pm + X\) at HERA thus allowing to probe for anomalous trilinear couplings among the gauge bosons. We discuss the next-to-leading order (NLO) QCD corrections to the photoproduction of W bosons with finite transverse momentum at HERA. The higher-order QCD corrections reduce the factorization scale dependence significantly and modify the leading-order (LO) cross sections by \(\pm {\cal O}(10\%)\).
